  • Anglo Coal - Case Study

    Acidic mine water treatment without lime South African Coal Estates (SACE) is a division of Anglo Coal and operates the coalmine at Landau Colliery in South Africa. Processing of the coal results in a sulphate-rich effluent. Part of the sulphate is removed with lime precipitation but this produces an effluent that is oversaturated with gypsum. As a result, scaling occurred ...

  • Hydraulic residence time and iron removal in a wetland receiving ferruginous mine water over a 4 year period from commissioning

    Analysis of residence time distribution (RTD) has been conducted for the UK Coal Authority's mine water treatment wetland at Lambley, Northumberland, to determine the hydraulic performance of the wetland over a period of approximately 4 years since site commissioning. The wetland RTD was evaluated in accordance with moment analysis and modelled based on a tanks-in-series (TIS) model to yield the ...

  • Fiscal risk to West Virginia's special reclamation fund

    This paper analyses fiscal risk to West Virginia's Special Reclamation Fund for abandoned mine lands and AMD water treatment from 1990 through 2003. I find that, despite tightening regulatory restrictions which have led to reductions in bond defaults there are continued risk to both revenue collections and expenditures. These include coal price variability, technological or regulatory change and ...

  • Everything you need to know about mining wastewater treatment

    Over the years, the mining and industrial areas have kept on occupying more remote locations, and because of this, the intensity and level of metals-loaded wastewater are raising gradually. The mounting levels of wastewater discharged from mining sectors are playing a pivotal role in environmental pollution’s and hence has become a key concern for the ecologists. To address such serious ...

  • HybridICE® filter: ice separation in freeze desalination of mine waste waters

    Freeze desalination is an alternative method for the treatment of mine waste waters. HybridICE® technology is a freeze desalination process which generates ice slurry in surface scraper heat exchangers that use R404a as the primary refrigerant. Ice separation from the slurry takes place in the HybridICE filter, a cylindrical unit with a centrally mounted filter element. Principally, the ...

  • Membrane fouling

    The Problem: Membrane water treatment is costly and complex due to the systems required to mitigate membrane fouling. Membranes have, therefore, been relegated to high value applications such as desalination and ultra-pure water needs. The systems used to mitigate fouling have a history of underperformance and high cost. EconoPure Solution: EconoPure has ...

  • Treatment of iron(II)-rich acid mine water with limestone and oxygen

    The main components of acid mine water are free acid, sulphate, and Fe2+. Limestone is the most cost-effective alkali that can be used for neutralization. The purpose of this investigation was to identify conditions where Fe2+ is removed with limestone and simultaneously oxidized with oxygen to Fe3+, in a polyvinyl chloride pipe under pressure. Gypsum ...

  • Optimizing the Slaking Process

    Poorly-slaked lime can have a major negative impact on lime consumption and the operating cost at an end-user’s site. The amount of lime used in the process is determined by a combination of slaking parameters. The optimisation of the slaking process will help drive operating costs down and also reduce CO2 emissions.  When the slaking of lime (ie, the conversion to calcium hydroxide ...
